Hello, is this a letter addressed to Demon Fortress?

Lin Gui couldn't be sure whether Roger did it on purpose.

Perhaps he simply didn't believe that Lin Gui and the other two would actually attempt time travel.

After all, even a legend like him couldn't do it.

So I just marked a general direction to get by.

However, according to the aerial reconnaissance results from Lin Gui—

In the center of that area, where numerous wandering spirits and demons resided.

There is indeed a small "vacuum".

A strange blank space where almost no spirits are active.

He couldn't help but think it was Avalon, even if he wanted to.

Picking up a charcoal pencil, Lin Gui quickly drew two straight lines on the map.

A path pointing to a blank area is the entry path.

Another route, diagonally crossing the empty area, is the evacuation route.

After he finished drawing, he looked up.

Under the dual vision of [Eye of the Underworld] and [Demon Eye].

Deep within the wailing corridor, the most dazzling crimson light...

Suddenly, it twitched very slightly.

Lin Gui's breathing suddenly stopped.

Through the thick fog and darkness that stretched for kilometers, he "saw" clearly.

That wasn't a mindless ball of light.

Rather, it is a vast, twisted entity, a composite of countless wailing souls...

Humanoid silhouette.

It seemed to have sensed a distant spy.

The crimson mass turned slightly and actually "looked" over.

Two hollow, blood-flaming holes pierced through layers of mist.

Their gray eyes met for a moment in the void.

Cold, brutal, almost tangible malice and deathly silence.

Following that gaze, it crashed into Lin Gui's mind!

Lin Gui groaned, his eyes instantly welling up with tears.

He abruptly closed his eyes, severing the connection to the [Eye of the Netherworld].

My back was soaked with cold sweat.

"What's wrong?" Xia sensed something was wrong and asked urgently.

Lin Gui took a deep breath and opened his eyes again, now calm.

"fine."

He wiped the cold sweat from his forehead and pointed to the evacuation route on the map.

"Just checking..."

"A 'big problem' we'll need to avoid later."

Recalling their exchange of glances, Lin Gui raised an eyebrow.

He picked up the charcoal pencil and drew on the original map, at a spot near the edge.

It was marked with a small, eerie acute angle.

Like an abrupt turn, or perhaps a warning.

This was not the first time he had "gazed" into that crimson spirit.

The other party... is very strange.

Judging by the "weight" of the soul...

The opponent was not the strongest spirit demon in the corridor.

It might even be the weakest of the legendary and epic beings that Lin Gui had just glimpsed.

Within the vision of the [Eye of the Netherworld], the situation deep within the Howling Corridor gradually became clear.

The number of demons was far less than expected.

But each one was so powerful it was terrifying.

Their souls take on different forms.

Some resemble giant, black pythons writhing and thrashing, coiled deep within the basin's rift valleys.

Some resemble a silent, burning, pale mountain of bones, radiating a chill that freezes the soul.

The crimson figure in the very center that had previously "looked back" at Lin Gui now appeared "small".

However, even the "weakest" one of them.

The solidity of its soul and the intensity of its light...

It also far surpasses all the living beings and demons that Lin Gui has seen since obtaining the Eye of the Netherworld.

Whether it's Freya, who is in the legendary mid-tier.

It's still the Epic-tier lower-rank Fortress Master Balin Heavy Hammer.

Although their souls blaze like the sun, they still belong to the category of "mortal".

And these spirit lords, entrenched in the Hall of Wailing...

Their "presence" has become almost a natural phenomenon.

Like a moving mountain, like a tangible calamity.

Lin Gui silently withdrew his gaze.

In my memory, there was only that fleeting silhouette glimpsed at the bottom of the Nether Sea.

That demigod demon Zathos caused the collapse of the entire western side of the continent.

Its vastness and terror surpassed even the monsters before them.

I recall the soul of the demigod Zarthos, which filled the entire abyss of the ocean.

Compared to that, these few epic demons seem insignificant.

He took a soft breath, his fingertips unconsciously tracing the acute-angled mark on the map.

Then I crossed it out with a pen.

Lin Gui knew in his heart that this mark actually had no practical use.

Because the other party was constantly following my movements.

That terrifying spirit lord, probably when I first started my reconnaissance...

They had already "noticed" themselves.

To be precise, it was "seen".

Lin Gui never believed that his undisguised observations from high above were anything special.

It can deceive the senses of any of the epic demons inside.

Just as he expected.

One's own strength is simply not enough to arouse the other party's "interest" in the slightest.

In his observation, the Wailing Corridor contained only a few enormous figures.

There are also many lower-ranking heroes and even weaker spirit demons roaming around.

They manage to barely survive on the edge of the epic lord's range of activity.

And the soul demon that rises from hero to legendary mid-tier...

We didn't see a single ghost.

It seems that higher-level demons have the characteristic of devouring lower-level demons to become stronger...

This also applies to spirit demons.

As long as you don't step into the area where the other person can "eat it without thinking".

There is basically no danger.

To demons, beings like humans, elves, and dwarves are...

It is no different in essence from other demons.

They are all just "energy bodies that can be consumed".

This is why the number of demons in the wild exploded, yet the city-states were still able to survive.

Like New Testament City, which has no protective barrier or large concealment array, it still survives under the cover of the Black Demon Forest.

Are the demons of the Black Forest trying to invade New Testament City and devour its hundreds of thousands of inhabitants?

Hey, I really don't want to.

Even if a demon devours hundreds of thousands of civilians, it cannot increase the demon's strength.

The strongest warriors in New Testament City are only high-ranking warriors.

This rank is commonplace in the Black Magic Forest.

Apart from those demons who lost in territorial battles and were forced to migrate.

For example, those that are defended year-round by the Twilight Fortress.

Or their living space is being constantly squeezed.

Like a deep-sea demon that has escaped from the ocean after a long period of silence.

Few demons would launch an active and organized attack on a city-state.

Because compared to their powerful and numerous kin in the wild...

The "energy" and "threats" provided by human and other living beings' habitats.

That's not enough to pique the devil's interest.

That's why Lin Guicai often said that the more dangerous the place, the safer it is to be weak.

To those epic spirit lords, he is now...

Like an ant crawling across your field of vision.

They can see it, but they would never deliberately open their mouths to eat it.

but……

Lin Gui's gaze returned once more to the crimson mass deep within.

Based on that brief "eye contact" and the seven hours of mutual observation that followed.

In the corridor, however, there was one... that seemed a little different.

Lin Gui's heart skipped a beat.

Could it be the [Eye of the Netherworld]'s ability to dispel spirits and demons?

Did it attract the attention of that special spirit?

However, the other spirit demons did not show much reaction.

Those low-level spirits that were close by and had direct eye contact with Lin Gui.

The moment she caught a glimpse of his grey eyes, she fled in panic.

Some demons are hidden by the terrain or dead trees and have never "made eye contact" with the forest ghosts.

They remained lingering in the same spot.

As for Soul Lords of Legendary rank and above...

They showed no reaction to the forest ghosts' "gaze" and remained indifferent.

The dispelling effect of the Netherworld Eyes relies on 'eye contact'.

Moreover, the rank that can be intimidated... is limited to below the legendary level.

As for why that guy paid special attention to him...

Lin Gui's gaze fell on the map, on the blank area he had circled.

He then scanned the outer edge of the blank area, marking several arcs with dotted lines.

That was the trajectory of the crimson spirit lord's prolonged stay and movement.

The trajectory closely encircles the blank area, almost forming a ring.

Lin Gui stared at the pattern and suddenly chuckled softly.

"Turns out he was a gatekeeper."

"It seems that Avalon also lacks a barrier to defend against demons."

"That's true, there's no barrier that can defend against spirit demons that can penetrate all physical and magical obstacles."

"If that's the case, then I don't need to knock on Avalon's door."
